长链非编码RNA（lncRNA）是一类长度大于200个核苷酸转录本,通过调控DNA、RNA及蛋白质的表达和功能,参与肿瘤发生、发展并发挥重要作用的RNA,近年来lncRNA成为恶性肿瘤早期诊断和预后标志物研究新的关注方向。Linc-UBC1作为一种新发现的lncRNA,在多种恶性肿瘤如肺癌、胃癌、结直肠癌、宫颈癌、卵巢癌、食管鳞癌等中异常高表达,可通过作为竞争性RNA（ceRNA）、参与信号通路等促进肿瘤细胞的增殖、迁移、侵袭、细胞周期进展、细胞凋亡和上皮间充质转化（EMT）等过程;高表达的linc-UBC1能够增加恶性肿瘤的耐药性,其表达水平与肿瘤分期、淋巴结转移和原发肿瘤远处转移呈正相关;linc-UBC1有望成为许多恶性肿瘤的新型的生物标志物、预后预测因子和治疗靶点,但其具体的调控机制仍处于研究的早期阶段,有待进一步深入研究。文章就目前linc-UBC1在恶性肿瘤发生和发展中的作用研究进展进行综述。

Long non-coding RNA（lncRNA）is a class of transcripts with a length of more than 200 nucleotides．It is involved in the occurrence and development of tumors and plays an important role by regulating the expression and function of DNA,RNA and protein．In recent years,lncRNA has become a new research direction for early diagnosis and prognosis of malignant tumors．As a newly discovered lncRNA,linc-UBC1 is abnormally highly expressed in a variety of malignant tumors such as lung cancer,gastric cancer,colorectal cancer,cervical cancer,ovarian cancer,and esophageal squamous cell carcinoma．It can promote the proliferation,migration,invasion,cell cycle progression,cell apoptosis and EMT of tumor cells by acting as a competing endogenous RNA（ceRNA）and participating in signaling pathways．High expression of linc-UBC1 can increase the drug resistance of malignant tumors,and its expression level is positively correlated with tumor stage,lymph node metastasis and distant metastasis of primary tumors．linc-UBC1 is expected to become a new biomarker,prognostic predictor and therapeutic target for many malignant tumors,while its specific regulatory mechanism is still in the early stage of research and needs further in-depth study．This article reviews the current research progress of linc-UBC1 in the occurrence and development of malignant tumors．

目的 基于SEER数据库分析三阴性乳腺癌（TNBC）的预后,并建立Cox回归临床预测模型且进行内部验证。方法 使用SEER*Stat软件（8.4.2版）筛选2010—2015年诊断为TNBC的病例,进行单因素和Cox多因素回归以及向后逐步回归分析,明确与生存相关的独立危险因素,构建预测TNBC患者3年和5年癌症特异生存（CSS）率的Nomogram图,并用受试者工作特征曲线,Harrell’s一致性指数,临床预测模型校准曲线以及决策曲线对该模型进行评估及内部验证,以评估该模型的临床预测效能。结果 共筛选出符合纳入标准的TNBC患者5 564例,按照7∶3的比例随机拆分为训练集（n=3 894）和验证集（n=1 670）。通过单因素,多因素分析显示TNM分期、放射治疗、化学治疗以及手术和其他治疗的先后顺序是与TNBC患者CSS显著相关的独立危险因素（P<0.05）。利用上述预后相关因素建立Nomogram图模型。训练集的C-index为0.731（95%CI：0.712~0.749）,验证集的C-index为0.719（95%CI：0.688~0.749）,训练集和验证集3年和5年生存ROC曲线的曲线下面积均>0.7,区分度较好,且校准曲线拟合良好。结论 TNM分期、放射治疗、化学治疗以及手术和其他治疗的先后顺序是TNBC的独立预后因素,基于此建立的Nomogram图临床预测模型区分度、准确度以及临床适用性较好,能较好地预测TNBC患者的生存预后。

Objective To analyze the prognosis of triple negative breast cancer（TNBC）based on the SEER database,and to establish a Cox regression clinical prediction model with internal validation．Methods Cases diagnosed with TNBC from 2010 to 2015 were screened using SEER*Stat software（version 8.4.2）,and univariate and Cox multifactorial regression as well as backward stepwise regression analyses were performed to identify the independent risk factors associated with survival,and to construct a clinical prediction model for predicting the three- and five-year cancer specific survival（CSV）of TNBC patients．Survival（CSS）rates of TNBC patients at 3 and 5 years,and the model was evaluated and internally validated using the ROC curve,Harrell’s consistency index（C-index）,clinical prediction model calibration curve,and decision-making curve（DCA curve）to assess the predictive efficacy of the model for clinical prediction．Results A total of 5 564 TNBC patients meeting the inclusion criteria were screened and randomly split into a training set（n=3 894）and a validation set（n=1 670）according to a 7∶3 ratio．By univariate,multivariate analysis showed that T-stage,N-stage,M-stage,radiotherapy,chemotherapy,and the sequence of surgery and other treatments were independent risk factors significantly associated with CSS in TNBC patients．The above prognostic-related factors were utilized to build a Nomogram plot model．The C-index was 0.731（95%CI：0.712-0.749）for the training set and 0.719（95%CI：0.688-0.749）for the validation set,and the areas under the curves of the 3- and 5-year survival ROC curves of both the training and validation sets were >0.7,which was a good differentiation,and the calibration curves were well-fitted．Conclusions T-stage,N-stage,M-stage,radiotherapy,chemotherapy,and the sequence of surgery and other treatments are independent prognostic factors for TNBC,and the Nomogram clinical prediction model based on this has good differentiation,accuracy,and clinical utility,and can better predict the survival prognosis of TNBC patients．
